Shockwave treated seed germination and physiological growth of Vigna mungo (L) in red soil environment

In the present study of eco physiological effects of lead nitrate was observed by taking a local cultivated cereal crop Vigna mungo (L). The germination data showed that there is a negative impact of concentration of lead nitrate on the germination of seeds. There is decrease in seed germination at higher concentration in comparison to control. Root and shoot growth of seedling was effected when exposed to high concentration of lead nitrate. Roots were more affected and much reduced than shoots. Morphologically they look different from normal roots by their size and shapes. Effect of different concentration of lead nitrate was visible in different pigment concentration of leaves. Lead toxicity inhibits chlorophyll formation which visually showed in degeneration of green pigments in shoots exposed to different concentration of lead nitrate. With the increase in concentration of the toxicant, the exposed seedlings showed a decline in chl-a, chl-b, total chl, carotenoid and pheophytin content in shoots. This was a clear indication that the fall in the growth rate, pigment content had direct impact on photosynthesis. Conclusively, our results show that lead at higher concentration decreases seed germination, chl-a, chl-b, total chl, carotenoid and pheophytin contents in the mung seedlings.Int. J. Appl. Sci.

The experiment was conducted in the Agronomy Laboratory of Agrotechnology Discipline, Khulna University, Khulna from 29th August to 17th September, 2009. The experiment was laid out in a Completely Randomized Design (CRD) with two factors and three replications. The aim of the experiment was to study the efficacy of three osmopriming agents viz ., NaCl, KC1 and CaCb with control on seed germination and seedling growth of three T. aman rice varities viz., BRRI dhan40, BRRI dhan41 and BINA dhan7. Among the chemicals CaCb showed best as osmopriming agents and it enhanced all germination parameters. BRRI dhan41 showed the best performance. Better root length and shoot length were observed in control. Seeds of BRRI dhan41 when treated with NaCl showed the highest germination percentage (98.67%), germination energy (88%), germination speed (96.83%), but vigor index (10.63) was found highest in BRRI dhan40 when it was treated with KC1. BRRI dhan41 produced the largest root (8.56 cm) when seeds were treated with NaCl. BRRI dhan40 (10.51 cm) and BINA dhan7 (10.53 cm) produced the highest shoot length at controlled condition and CaCl2 treated seed, respectively. DOI: http://dx.doi.org/10.3329/jbau.v10i1.12013 J.

Plant Characteristics

Seeds of three flue-cured tobacco (Nicotiana tabacum L.) varieties, Hicks Broadleaf, Yellow Gold, and Canadel, were soaked for 1, 2, 3 or 5 hours in a saturated solution of diethyl sulphate, a chemical mutagenic agent, to increase variability of plant characteristics. Diethyl sulphate had a detrimental effect on both extent and rate of germination; each decreased with length of soaking period. Seedlings from treated seed grew more slowly than controls.

Rare Plant Species

Antiaris toxicaria (Pers.) Lesch. is one of the species of ecological importance distributed in Western Ghats and other parts. This species is considered as one of the threatened species and it needs conservation. The information on fruit and seed trait variation and germination attributes are scanty. Such database is useful for afforestation programme as well as for augmentation of rare plant species in their natural habitat. For the present study, 10 open pollinated trees distributed in Devade forest of Sakharpa were marked. April month was the peak fruiting period and healthy fruits were collected from the ground. Fruit and seed traits were found to be varied significantly among trees, where fruit length ranged from 21.50 to 24.71 mm and fruit weight ranged from 3.64 to 4.07 g. Similarly, seeds length (14.01 -15.09 mm), seed thickness (12.15 -13.04 mm) and seed weight (1.20 â€“ 1.57g) also showed significant variation among 10 trees. Field observation showed that there was a poor regeneration in this species at studied site. Therefore, germination study was conducted at nursery condition by imposing several pretreatments. Among eight treatments including control, soaking seeds in water for 24 hrs (T2) resulted in better germination of 38.0% as compared to others. In T2 seed germination started at 16 days after sowing and completed within 42 days. Potting mixture of red soil with saw dust in 30:70 ratio improved seed germination about 20 % as compared to red soil media.

The Difference

The effectiveness of solid matrix priming (SMP) and seed brushing was further evaluated by using an thermo-gradient table (Seed Processing, Holland) set at 10 different temperatures from 12 to 30 °C. Intact or brushed seeds of gourd (Lagenaria siceraria) were primed with Micorocel E (Celite Corp.) at 25 °C for 3 days in the mixture of 10 seed: 1 Microcel E: 3 water, by weight, and the primed seeds were dried again for long-term storage. SMP treatment significantly increased earlier seed germination at all temperatures. However, the difference in seed germination rate between intact and SMP-treated seeds was most pronounced at somewhat lower temperatures of 18-22 °C. SMP-treated seed showed about 20% final germination rate at 12 °C, whereas intact seeds did not germinate at all. Seed brushing treatment itself did not influenced the germination rate. However, brushing treatment before SMP treatment significantly increased the SMP effect. Combined use of chemicals in solution further increased the early germination. Details of various seed treatment methods will be presented.

An experiment was carried out during the year of 2010 - 2013 at Algarah farmer field (1740 m asl), under the aegis of Uttar Banga Krishi Viswavidyalaya, to evaluate the effect of different growth hormone on seed germination of jatamansi, and assess the effect of date of transplanting and plant geometry on its economic and biomass production under the mid hill condition of West Bengal. An experiment was with various growth regulators on Valeriana jatamansi revealed that maximum seed germination was observed with KNO3 (0.2%) (70.00±1.10), and significantly superior to rest of the hormonal treatments except Kinetin 200 ppm. This recorded 124 % more seed germination over the control. GA3 200 ppm took least time to start germination and was at par with Kinetin 200 ppm and KNO3 (0.2%) treated seed. Transplanting of seedling during the first week of July gave significant response on fresh aerial biomass (g/plant) at 6 months only. However, plant spacing gave significant response all the stage of observation, and maximum aerial biomass was recorded with spacing of 30 x 45 cm, and was at par with 30 x 30 cm plant spacing. Maximum underground biomass was recorded with July transplanting with 30 x 45 cm. Maximum underground rhizome biomass was recorded with 30 x 45 cm spacing, and was at par with 30 x 30 cm spacing at 9 and 18-month stage of observation. Root biomass failed to produce any significant response with time of transplanting. However, maximum root biomass was recorded with July transplanting. More root growth was recorded with 30 x 45 cm and was at par with 30 x 30 cm spacing during 15 and 18-month observation.
